Surface reports no supported texture formats for adapter {:?

Error message

Surface reports no supported texture formats for adapter {:?}

What it means

Raised in the internal `WgpuRenderer` constructor when `surface.get_capabilities(&adapter)` returns an empty formats list, so no texture format (Bgra8Unorm/Rgba8Unorm preferred) can be chosen. Means the adapter and surface are fundamentally incompatible (wrong adapter for the surface's display, or device removed).

Solutions

1. Re-request the adapter with compatible_surface set to this exact surface.
2. Recreate the WgpuContext if the device was lost (DeviceLost/OutOfMemory).
3. Verify the surface was created with the same instance as the adapter.
4. Log the adapter backend and name to diagnose driver/platform-specific incompatibilities.
